    This is similar to <span class="function"><a href="function.pg-send-query-params.html" class="function">pg_send_query_params()</a></span>, but the command to be executed is specified 
    by naming a previously-prepared statement, instead of giving a query string. The 
    function&#039;s parameters are handled identically to <span class="function"><a href="function.pg-execute.html" class="function">pg_execute()</a></span>. 
    Like <span class="function"><a href="function.pg-execute.html" class="function">pg_execute()</a></span>, it will not work on pre-7.4 versions of
    PostgreSQL.
